To all whoa-tit may coqncm: I

Be it knownt'hat I, Edwin Rf Biii'dimn,

a' citizen off'the United States; resident of Minneapolis, county'ofHennepin, State of hiinncsota, have invented certain new and usefulImprovements in Wheels, of which the followingis' a specification:

My invention relates to the tread surface of a wheel ancl particularlythose of traction type, and the object of my invention is to providemeans for"increasi'ng"or decreasing the width of tread of a machinewithout the necessity of substituting wider or narrower wheels.

My specific object in this case is to adapt a machine of the gardentractor type for cultivating between rows of plants, the machinestraddling one or more rows and the variation in the width of themachine adapting it for different distances between the rows.

The invention consists generally in various constructions andcombinations, all as hereinafter described and particularly pointed outin the claims.

In the accompanying drawings forming part of this specification,

Figure l is a vertical sectional view through a traction wheel embodyingmy invention,

Fig. 2 is a side view of a portion of the wheel,

Fig. 3 is a detail sectional view showing the manner of securing the rimto the wheel.

Fig. 4 is a detail sectional view, showing another manner of mountingthe rim to increase to a still greater extent the width of the machine,

Fig. 5 is a plan view, showing the machine in position for work betweenthe rows of plants, with the tread of the wheel adjusted tor wide spacesbetween the rows,

Fig. 6 is a similar view, showing the tread of the wheels adjusted fornarrow spaces,

Fig. 7 is a view, showing the rows of plants sixteen inches apart.

In the drawing, 2 represents an axle, 3 a fly wheel and 4 a hub havingan internal gear ring 5 that is provided with a series of radiating lugs6. These lugs are provided on their opposite faces with seats 7 in theplane substantiall of the gear ring. 8 is a rim having traction ribs 9thereon at intervals and provided with inwardly projecting lugs 10 whichare adapted to fit the seats 701v eitlie'r side of the lugs G andaresecured theretoby suitable means, suchas bolts 11. W hen-theriin isplaeed' on the gearring in theosition shown in Fig 1 and secured, itisev'ident that the treadof the machine will bewider'thmr when the: rimis reversed and securedin the" position shown in Fig. 3, and when astill'greater variation'fis' desired, the rinrma'y' be placed in theouter seats of the lugs (3, as shown in Fig. *1, thereby setting the rima distariee reater than asshown in F igi 1, equal to the thickness ofthe lugs; or, when desired, the rim may be secured to the seats of theinner faces of the lugs, as indicated by dotted lines in Fig. 4.

To make these changes or reversals, it is only necessary to remove thebolts and shift the rim from one side of the lugs to the other, orreverse it entirely, according to the width of tread of the machinedesired.

In Fig. 5 I have shown the rims mounted on the wheels to adapt themachine for operating where a comparatively wide space is providedbetween the rows of plants, the adjustment of the rims bringing thetread of the wheels a sutiicient distance from the plants to prevent anydanger of injury thereto, while the cnltivators or groundworkingimplements 1:2 mounted in carriers 13 are positioned to straddle therows of plants and cultivate as near as may be desired to them.

In Fig. 6 the machine is shown with the plants arranged in rows withnarrower spaces betwen them, the position of the rims of the wheelsbeing reversed to acconnnodate the machine to the reduced space betweenthe rows.

In Fig. 7 the rows of plants are shown sixteen inches apart, for whichspace the machine may be accommodated, while in Figs. 5 and 6 the rowsare eighteen and twelve inches apart respectively.

By making the rims of the traction wheel reversible, I am able toincrease or decrease the distance between the tread of the wheels andthereby adapt the machine for cultivating plants with varying distancesbetween the rows.

In various ways the details of construction herein shown and describedmay be moditied and still be within the scope of my invention.

I claim as my invention:

1. A traction wheel comprising a hub having an internal gear ring formedthereon, a rim having peripheral traction ribs thereon and a series ofinwardly projecting members mounted 011 said rim at one side of thevertical axis thereof and said ring having means for securing saidmembers thereto upon either side of the vertical axis of said rmg.

52. A traction wheel comprising a hub 10 having an internal gear ringformed thereon provided with a series of lugs radiating therefrom atintervals, said lugs having seats in their opposite vertical faces inthe plane substantially of said gear ring, a rim having peripheraltraction ribs thereon and provided With a series of inwardly projectinglugs adapted to fit the seats of said radiating lugs on either sidethereof, and

bolts passing through said lugs for securin them together.

3. A traction Wheel comprising a hub having an internal gear ring formedthereon provided with members radiating therefrom at intervals, saidmembers having seats in their opposite vertical faces in the planesubstantially of said gear ring, a rim having peripheral traction ribsthereon and provided with a series of inwardly projectingl membersadapted to fit the seats of said 1a iating members on either sidethereof, and means for securing said members together.

In witness whereof, I have hereunto set my hand this 13th day ofFebruary, 1917.

EDWIN R. BEEMAN.
